Abstract
A harmonic ring gear system can include at least one inner gear with external toothing, the at least one inner gear defining an axis of rotation; at least one outer gear with internal toothing arranged concentrically to the at least one inner gear about the axis of rotation, the internal toothing spaced apart from the external toothing; a pin ring positioned between the at least one inner gear and the at least one outer gear, the pin ring comprising a multiplicity of pins; and a rotary transmitter configured to lift a portion of the pins of the multiplicity of pins off the external toothing and press the portion of the pins into the internal toothing.
Claims29
Harmonic pin ring gear system comprising an input shaft and an output shaft, wherein said harmonic pin ring gear system has the following features:
- two outer gears, each with internal toothing,
- a single inner gear with external toothing arranged concentrically to a first outer gear and inside said first outer gear in axial direction, and
- a drive means extending between the two outer gears and the inner gear comprising a pin ring formed as one part in circumferential direction and a multiplicity of pins that protrude laterally in axial direction from the pin ring,
- a rotary transmitter for lifting the drive means off the external toothing of the inner gear and pressing the drive means into the internal toothing of the outer gear.
A pin ring arrangement, comprising:
- a multiplicity of pins;
- and
- a pin ring for holding the pins and a transmitter for exerting a radial, outwardly directed force onto the pins;
- wherein the transmitter is arranged inside the pin ring and the pins lie at least predominantly on an outer circumference of the transmitter.
